Poor gas mileage on my 1993 dodge caravan


If you want fuel economy then dump this beast and buy a nice peugeot or citreon picasso diesel manual then you will get around 30 mpg around town and anything up to 70 mpg on a run ,try paying our fuel prices and this nice typical american petrol gas burner would be delegated to the classic car sunday drive out like my jag with its 4lt engine i can only afford to take it out once a month or so on a jaguar club run around ,other than that its my ford diesel manual escort with its 0 to 60 in 15 minutes but it only uses one tank of fuel a month.

Wont start trying to locate the fuel pump jag. xj6


Hello.
Most cars have the fuel pump on the drivers side right in front of the rear wheel tucked up into the body panel. You can easily find them by tracing the thin fuel line from the tank until you get to the fuel pump. Hope this helps!

My jag wont start


It could be an ignition related issue or fuel.
When it doesn't start does it crank, do you have the ignition lights?
The most common problem of intermittant no star probems is the crank sensor on the front of the engine, they can break down over a period of time and fail when warm. if not then I would fit a fuel pressure guage to the car and run it. Then see what the reading is when warm. If it is nothing (should be 38-40) then I would replace the fuel pump relay.
The fuel pumps typically don't fail intermittantly, they just fail!

Jaguar xj6 1991 2.9 manual


2 things, first of all teh distributor cap and rotor go bad causing the car to have spark but not fire, secondly you need to make sure that you are getting fuel to the engine bay, if not then it could be the fuel pump.

In regard to the other gentlemans question, starts but cuts out I would start with the same process and open your fuel flap and make sure there is no water around the filler area as it sounds like you could also have water in your gas. (there is a drain next to the filler neck and it gets clogged over time, then when it rains or you wash your wash, that area fills with water and seeps into the tank)
